TPS53681: NOT ABLE TO PROGRAM NVM

Part Number: TPS53681

Hi All,

In the tps53681 mutiphase datasheet, the (USER_DATA_00 - USER_DATA_12 ) is mentioned as read and write only registers. But we are not able to write through i2c commands.i.e.., B0h - BCh. Please help us to resolve this issue and let us know if any sequence to be followed for writing these registers.
